Question

Increase the number 150 in ratio 5:7 . I want correct answers​. Please give an explanation also in the question.

Answer 1

Step-by-step explanation:

5:7 is nothing but 5/7.

so the number 150 has to be increased by 5/7.

convert this into equivalent fraction.

5/7 = (5×14.28) / (7×14.28) = 71.4/100 or 71.4%

(I've taken 14.28, it's roughly that much since 100 isnt perfectly divisible by 7).

so increase 150 by 71.4%

which is,

150 + (150 × 71.4%)

= 150 + 107.1

= 157.1
